What is funnel analysis?

Funnel analysis is the process of tracking how users move through a series of steps toward a desired goal and identifying where they drop off, why they drop off, and where improvements can increase conversions.

Key elements of funnel analysis:

1. Define funnel stages – Identify the important steps in the customer journey.
2. Track users at each stage – Measure how many visitors reach each step.
3. Measure conversion rates – Calculate the percentage of users progressing from one stage to the next.
4. Identify drop-offs – Find stages where a significant number of users leave.
5. Investigate causes – Analyze potential issues such as poor UX, unclear information, slow loading, unexpected costs, or checkout friction.
6. Prioritize improvements – Focus on the stages offering the greatest opportunity for improvement.
7. Test changes – Use A/B testing and other CRO methods to determine whether changes improve performance.

Example

An ecommerce funnel might look like:

1,000 visitors → 400 product views → 150 add to cart → 80 checkout → 50 purchases

If many users drop between checkout and purchase, the business can investigate payment problems, unexpected costs, complicated forms, or lack of trust signals.

In CRO, funnel analysis helps businesses identify where customers are being lost and determine what should be optimized to increase the overall conversion rate.
